Google does not name a plan for custom apps in the Gemini app. Google AI Plus is $4.99 a month, AI Pro $19.99 and AI Ultra from $99.99, in the US.
Brew is billed on emails sent and AI credits, with unlimited contacts on every plan: a free trial with 500 AI credits and 1,000 sends, then Growth at $99/month for 10,000 AI credits and 50,000 sends.
The Gemini app connects to remote MCP servers as custom apps for adults in the US on personal Google accounts, in English. Work and school accounts cannot add custom apps yet.
Start a free trial, paste your website so Brew writes your brand files, and connect your sending domain.
On gemini.google.com, open Settings → Connected Apps, then Add a custom app under Custom apps.
Enter https://brew.new/api/mcp, click Next and sign in to Brew.
Type @ in a prompt and pick Brew. Gemini asks you to confirm any write action, and Brew asks before anything sends.
Connect Claude, ChatGPT, Cursor or Grok over MCP and your agent gets every Brew tool. It designs emails from your brand, builds audiences, runs automations and schedules sends. OAuth and organization-scoped MCP connections ask you to confirm live sends and launches. Brand-scoped API keys can execute permitted calls without the MCP confirmation step.
Paste your website and Brew writes your brand into two files your agent reads for every email. Describe the email and it appears on the canvas, ready to edit by hand or in chat.

Partly. Gemini can draft emails in Gmail with Help me write, make images and plan campaigns. On its own it does not design a finished, on-brand email, hold your contacts, send from your domain or run automations.
Not marketing email. Help me write drafts emails in your own Gmail and you send them one at a time; Gemini has no contact list, unsubscribes or sending domain.
Connected to Brew, Gemini sends campaigns from your own domain to your audiences, with unsubscribes handled, after you approve.
The Gemini app connects to remote MCP servers as custom apps for adults in the US on personal Google accounts, in English. Work and school accounts cannot add custom apps yet. Open Connected Apps: On gemini.google.com, open Settings → Connected Apps, then Add a custom app under Custom apps. Add Brew: Enter https://brew.new/api/mcp, click Next and sign in to Brew. Ask Gemini for an email: Type @ in a prompt and pick Brew. Gemini asks you to confirm any write action, and Brew asks before anything sends.
Google’s help names no plan: custom apps work in the Gemini web app for adults in the US on personal Google accounts, in English. Work and school accounts cannot add them yet, so Gemini in Gmail for Workspace cannot use Brew today.
Gemini writes good copy, but on its own it does not design the email from your brand. Brew does: it writes your brand into files your agent reads for every email, then designs the layout, copy and images and tests how it renders.
No. Over OAuth, Brew asks you to confirm before anything is sent or goes live, so the assistant drafts and you approve.
Google does not name a plan for custom apps in the Gemini app. Google AI Plus is $4.99 a month, AI Pro $19.99 and AI Ultra from $99.99, in the US.
